World first: Folding Glass Door SL 97 Timber / Aluminium

A very high thermal insulation characterizes the SL 97 folding glass door of timber / aluminium. Laminated timber profiles with 96mm in depth, an additional insulation layer and triple glazing achieves a U value of 0.80 W/m2 K and allow a reference to the passive house standard.

All components are tested to be environmentally friendly.
